"I believe the engineering judgement that took 30 years to build deserves a system that outlives the engineer who built it."— Ian Griffiths, Founder
We sit beside you for 12 months. By the end, your judgement is locked into the firm. The firm runs without you on every quote, proposal, and senior decision.
Same 12-month engagement. Different headline outcome depending on which founder you are.
The Bottleneck Owner/Manager
Saturdays gone two years
Your weekends back permanently. Your firm grows faster than before.
Concerned about Margin
T&I work commoditising
You charge premium pricing because what you ship cannot be commoditised.
Losing too many bids
Lost a £180k framework to a larger competitor
You win frameworks against competitors twice your size.
Continuity/succession gap
Two seniors retiring in 24 months
Your firm survives the senior-engineer retirement cliff with no loss of judgement.
The Exit Focused
Firm runs on tribal knowledge
Your firm sells at 4-5 times revenue, not 0.5 to 1 times, because the senior judgement is in the system.
We do not have testimonials yet. We have something more useful: the principles our offer rests on, in the words of the people the world recognises as the authorities on each one.
If your business requires your presence, you don't have a business, you have a job. And it's the worst job in the world because you're working for a lunatic.

We can sign three founders at £25,000 a year. After those three, the rate goes up to £40,000–£45,000.
"Every senior decision still flows through me."
"The firm slows when I'm out for a week."
"AI is everywhere, but I can't see what to do with it from where I'm sitting."
Most founders try to fix it by hiring another chartered engineer. £50,000 to £75,000 a year fully loaded. 18 months to recruit. If they leave, the judgement walks out the door with them.
Legacy turns the senior judgement you already have into a system the firm runs without you. £25,000 a year. Yours to keep.
"A senior chartered engineer costs £50,000–£75,000 a year fully loaded, and takes 18 months to recruit. Legacy gives your firm a senior-judgement engine for £25,000 a year, embedded in 12 months, and you keep what we build forever."
A 30-minute call. We find the bottleneck in your firm and tell you what to do about it.
Two weeks of work. We look at your firm and write down what to fix, in what order. Best if you don't have a delayed quote we can ship right away.
We take a real quote that's been sitting on your desk and finish it in 14 days. We do the first pass. You review and refine. The prospect sees the whole process. Proves the method works on a real piece of your business.
A three-month engagement before the full year-long build. For founders who want to see the method at scale before committing to twelve months.
Our 12-month side-by-side build. Turns the founder's senior judgement into a system the firm runs without him.
A custom engagement for large infrastructure clients and data-centre operators. Different scope, different funnel. Talk to us directly.
We take one of your real quotes, the one stuck on your desk right now, and finish it for you in week 2. No charge. You get the finished quote out the door, your client gets a fast answer, and you see the method working on a real piece of your business inside the first month.
Every three months, we write a one-page score for the people who own and run the firm with you. Two numbers, no more. Senior-engineer hours saved this quarter. What the firm would be worth at sale today versus three years from now. We walk your board through it for an hour, in normal money words.
Every standards override your chartered engineer signs off on during the year gets captured in your firm's working binder, organised by the standard it relates to (EN 50522, EN 62305, IEEE 80, ENA TS 41-24, and the rest). By month 12 you have a living playbook of how each standard actually plays out on your firm's bids; the edge cases, the assessor fights, the interpretations that won work and the ones that lost it. Plus quarterly notes from the committee table: what's being debated in the next revision, what's coming, what got rejected and why. Yours to keep forever, even if you walk at month 12. AI can summarise a standard in thirty seconds. AI cannot capture how your senior engineer interprets it on a tight bid with imperfect data. This bonus does, and turns the year's accumulated judgement into a permanent firm asset.

A 12-month engagement at director level needs more than a one-line refund clause. Three guarantees stack to cover three different time-windows of risk.
Any time in the first 90 days, you can walk. Full refund of the unused balance. No questions, no exit interview, no notice period.
Three concrete things happen on three specific dates, or you get money back.
Miss any milestone, money back, pro-rated.
By month 12, your firm will ship at least one quote, proposal, or major engineering decision without you personally signing it off at senior grade. If it doesn't happen, refund of the final quarter.
If you refuse to delegate at any point in the 12 months, this guarantee voids. Otherwise every founder could trigger the refund by simply refusing to engage with the work.
None of these is rare on its own. The combination has not been built into a single firm before.

| Option | What you get | What it costs | Why we're different |
|---|---|---|---|
| Another senior chartered engineer hire | One more body | £50–75k/yr fully loaded · 18-month recruit | Half the cost. No 18-month recruit. Asset, not headcount. |
| IET CPD courses | Episodic credentialed training | Per-course | Trains people. We train the firm. |
| Big 4 transformation consultancy | Slides | £100–500k | We read the HV earthing and lightning standards. They don't. |
| Generic AI consultancy | Decks and chatbots | £20–100k | No HV depth, no standards fluency, no chartered-engineer override. |
| Specialist tools (XGSLab, ETAP) | Software | Per-licence | Tools need senior judgement to wield. We sit one layer up. |
| Founder absorbs the bottleneck personally | Saturdays | Years of weekends | The status quo is the most expensive option on the list. |
